BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Euphorbia plant, an interspecific hybrid botanically known as Euphorbia pulcherrima Willd. ex Klotzsch×Euphorbia cornastra, and hereinafter referred to by the cultivar name ‘Bonpri 1049’.

The new Euphorbia plant is a product of a planned breeding program conducted by the Inventor in Yellow Rock, New South Wales, Australia. The objective of the program is to create and develop new interspecific Euphorbia plants with compact, upright and mounded plant habit and attractive flower bracts.

The new Euphorbia plant is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ex Klotzsch×Euphorbia cornastra ‘Bonpri 515’, disclosed in U.S. Plant Pat. No. 25,587. The new Euphorbia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Bonpri 515’ in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia on Mar. 1, 2012.

Asexual reproduction of the new Euphorbia plant by terminal vegetative cuttings in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia since March, 2012 has shown that the unique features of this new Euphorbia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Euphorbia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bonpri 1049’. These characteristics in combination distinguish ‘Bonpri 1049’ as a new and distinct Euphorbia plant:

-   -   1. Compact, upright and mounded plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Inflorescences with bright red purple-colored flower bracts.     -   7. Good post-production longevity.

In side-by-side comparisons conducted in Yellow Rock, New South Wales, Australia, plants of the new Euphorbia differ primarily from plants of the mutation parent, ‘Bonpri 515’ in the following characteristics:

-   -   1. Plants of the new Euphorbia are more compact than plants of         ‘Bonpri 515’.     -   2. Plants of the new Euphorbia are more freely branching than         plants of ‘Bonpri 515’.     -   3. Plants of the new Euphorbia have smaller leaves than plants         of ‘Bonpri 515’.     -   4. Plants of the new Euphorbia are more freely flowering than         plants of ‘Bonpri 515’.     -   5. Inflorescences of plants of the new Euphorbia have fewer         flower bracts than inflorescences of plants of ‘Bonpri 515’.     -   6. Flower bracts of plants of the new Euphorbia resist fading         better than flower bracts of plants of ‘Bonpri 515’.

Plants of the new Euphorbia can be compared to plants of the Euphorbia pulcherrima Willd. ex Klotzsch×Euphorbia cornastra ‘Bonpri 1069’, disclosed in U.S. Plant patent application Ser. No. 14/999,328. In side-by-side comparisons, plants of the new Euphorbia differ primarily from plants of ‘Bonpri 1069’ in flower bract color as plants of ‘Bonpri 1069’ have light pink-colored flower bracts.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and described herewith in detail were grown during the autumn in 12-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Euphorbia production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fourth Edition, 2007, except where general terms of ordinary dictionary significance are used.
